In 2011, we saw earthquakes, tsunamis, a royal wedding, a continued stagnant economy and civil uprisings in the Middle East and at home. What can beat all that in 2012? Perhaps only the end of the world.

The myth that the Mayan calendar predicts the end of the world on Dec. 21, 2012, has largely been debunked. But psychics and astrology experts say that in 2012, we can expect world leadership changes, growth in the economy — and even an explosion that will rock San Francisco, but not because of an earthquake.

Maralyn Burnstein, a San Francisco-based astrologist, said The City’s astrological charts for next year are aggressive. She said the way the planets, including Jupiter and Uranus, are aligned means a lot of combustion could happen in The City.

“San Francisco is right in the middle of massive death and transformation,” Burnstein said. “We’re about as bad as it’s going to get. And it’s fairly grim for transit.”

Burnstein said the work happening on the Central Subway, which she called the subway to nowhere, will prove to be a problem in 2012.

“Whoever is overseeing the work in the tunnel needs to contact all the utilities at once,” she said. “Someone is out of the mix [on the work], and if they continue to be out, the risk is pretty high. There is the possibility of explosion from a spark.”

Burnstein said the idea that the world will end in one year, though, is “a bunch of hooey.”

The violent force that Burnstein sees in 2012 also is vivid in LaMont Hamilton’s visions. The self-named “World Psychic” said almost every major country in the world will have a new leader in 2012.

“In 2012, we’ll see more tumbling and bring-down of major governments and corporations,” Hamilton said. “We saw it with Libya, we’ll see it with Venezuela, and China will fall. I’ve been predicting Kim Jong-Il’s death for two years.”

But 2012 is “nowhere near” the end of the world, according to Hamilton.

He said his predictions come in the form of visions — a picture in his mind with objects he must interpret.

Hamilton’s visions are always accurate, he said, but it’s the interpretations that can be off.

“The image and the information I get is never wrong,” he said. “But it’s a still image I see. I don’t use instruments or cards; it’s up to me to interpret.”

Dr. Tracey Wilen-Daugenti -- the Vice President, Managing Director of the Apollo Research Institute -- and her research team use data and statistics to predict what the world will face in the future. She said based on research, 2012 will be a big year for health care, women, small business and education.

“The workforce of today is not employable tomorrow,” Wilen-Daugenti said of education in the coming year. “The data shows we need to have degrees and skills and certification to climb in salary and avoid unemployment, and that’s what will be pursued next year.”

Though these experts had varying opinions and insights on the timing of much of what is to come, it’s not all doom and gloom in 2012.

All three experts agreed we as a country can expect the economy to begin to turn around in the fall.

“We will begin to get better after July,” Burnstein said. “We’ve made it through so far doing pretty well, and I think we’ll start to see it getting better.”
